For the time being, ISPA will take over the IPv6-to-IPv4-tunnel to 6WiN. Hopefully DFN is transforming 6WiN into a network that uses their IPv4 network. There are plans going on to use the GWiN MPLS core to achieve this. This way, we could use the native IPv4-only connection for both IPv4 and IPv6. In addition we will add a second native connection to the IPv6 pilot project of T-Com in the near future.
